When I asked my initial question to B&W, I also inquired about the possibility of a higher rated hitch in the future. Basically was told they have no plans to do so.
Just have to wonder why.
B&W is like that.  They will fight the idea of adding new product for a long long time, despite customer demand for it, but will eventually succumb and end up making a great product to fill that market need.  
They did the same thing with the slider hitch.  They fought the idea for several years, refused to come out with a sliding fifth wheel hitch for short bed trucks, but finally ended up coming out with a very good sliding fifth wheel hitch.  
So far, they have fought the idea of coming out with an air ride fifth wheel hitch.  My guess is, eventually, they will have an air ride hitch in their product line.  
Likely the same with a 25k rated hitch to fit all 3 trucks brands' of fifth wheel prep packages, they'll make one, eventually.
They're just a very conservatively run company and very slow to grow their product line.
